Proclinic Expert Root Canal Sealer
gives a hermetic seal with long-lasting strength thanks to its excellent solubility
and outstanding dimensional stability.
Proclinic Expert Root Canal Sealer is compatible with either standard or warm gutta-percha
obturation techniques. In the case of warm gutta-percha, it can be applied using:
The antibacterial effect of
Proclinic Expert Root Canal Sealer
combined with quaternary ammoniummacromolecules and their ability to inhibit
new biofilm formation was evaluated in an existing
Enterococcus faecalis
biofilm.
Incorporation of these macromolecules produced significant reductions in
new biofilm formation of between 25% and 72% and reductions in existing
biofilm viability of 20% to 36%.
OUTSTANDING,
LONG-LASTING SEAL
Fluorescence microscopy images of live (green) and dead bacteria (orangey red) taken
at different concentrations of quaternary ammonium incorporated onto epoxy sealer discs:
A) control group (0%); B) 0.4% w/v; C) 0.8% w/v; D) 1.6% w/v; E) 3.3% w/v.
Mean results (± SD) for
de novo
biofilm formation at the quaternary
ammonium concentrations incorporated onto epoxy sealer discs and
for the control (0, 0.4, 0.8, 1.6 and 3.3% w/v). Results correspond to
the optical density (OD) measured at 595nm.
Mean results (± SD) for the effect of different concentrations of
quaternary ammonium incorporated onto epoxy sealer discs and in
the control (0, 0.4, 0.8, 1.6 and 3.3% w/v) on biofilm viability.
Results are expressed as the live/dead bacteria ratio.

The incorporation of quaternary ammoniummacromolecules onto epoxy
sealer discs may be an effective method for preventing new bacterial
biofilm formation in treated root canals.
